SPECIFICATION forming part of Letters Eatent No. 652,651, dated June 26,1900.

Application filed December 20,1899. Serial No. 741,002. We model.)

T0 all whom it may concern:

Be it known that we,CHARLns W. THoMAs, J AMES J. THoMAs, and WION P.THoMAs, citizens of the United States, and residents of Sawyer, in thecounty of Orleans and State of New York, have invented a new andImproved BeanOleaner, of which the following is a full, clear, and exactdescription.

The purpose of this invention is to provide a superior means forscreening and cleaning beans and the like, to which end we provide ascreeningmill combined with a brush, by which latter device the beansare polished and discharged from the machine. 1

This specification is the disclosureof one form of our invention, whilethe claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is aside elevation of the invention. Fig. 2 is a longitudinalsection thereof. Fig.

.3 is a cross-section on the line 3 3 of Fig. 2,

and Fig. i is a detail perspective View of one of the bearings to behereinafter described.

The machine has a framing 5, which may be of any desired sort, on eachside of which are mounted two standards 6, which support the box orcasing 7 of the screening-mill, the standards being made of thin wood,so that the box may be shaken or oscillated from side to side in theusualmanner. On the box 7 is mounted a hopper 8, in which the beans tobe cleaned and polished are placed. WVithin the box 7 is a blank orplate 9, inclined like the box. At the upper end of the blank 9 avertical wall 10 is arranged, leaving a passage between the blank 9 andwall 10, the size of which may be regulated by a gate 11, mounted in thebox, as shown. A blower 12 is mounted on the base or framing 5 and hasits nozzle formed with a flexible portion 14:, which discharges into thebox 7 directly below the hopper 8, so that the beans falling from thehopper drop past the nozzle 14, and the blast from the nozzle blows thelighter impurities which are with the beans past the gate 11 and ontothe blank or plate 9, down which such impurities gravitate to adischarge-spout 15, carried by the box 7.

A sieve 16 is mounted in the box below the blank 9 and paralleltherewith, on which sieve .the beans from the hopper 8 fall, the beanspassing through the sieve, the impurities being retained by the sieveand discharged from its lower edge into the spout 15. Below the sieve 16a second sieve 17 is arranged within the box or casing 7, and this sieveis of such mesh that the beans will not pass through it, the sieveconducting the beans to a spout 18,

by means of which the beans pass from the screening device. Suchimpurities and other foreign matter as pass through the screen 17 aredelivered upon. the imperforate bottom 19 of the box or casing 7, fromwhich they are discharged by a spout 20, passing laterally to Fig. 4. Ashaft 2 is mounted on pedestals 25, supported by the base, and is drivenby a belt 26, which passes over a pulley 27 on the shaft 21 and a pulley28 on the shaft 24. This shaft 24 has a crank 29, to which is attached alink 30, connected with the box or casing 7, so as to impart a shakingmovement thereto. The box or casing 7 is guided and steadied in itsmovement by links 31, which are mounted to swing on a rigid portion ofthe framing, as shown, and have pivotal con nection with the box orcasing 7 at the re spective sides thereof.

Mounted on the base 5, directly below the spout 18 of the screeningdevice, is a circular casing 32, which is provided with an opening inits top, through which projects a large feedpipe 33, arranged in closeproximity to the spout 18, so as to receive the beans from the spout.This feed'pipe 33 leads to the interior of the casing 32 and is attachedto and carried by the brush 35. Within the casing 32 is arranged ahorizontally-disposed screen 34. On this screen the beans fall and arecleaned by the revoluble brush 35, fastened on a vertical shaft 36through the medium of a setscrew, as shown, so that the brush 35 may be36 and turns with thesame.

adjusted vertically on the shaft, causing the brush to properly engagethe sieve 34. This cleans the beans, thoroughly rolling them over andover on the sieve, and finally discharges them by centrifugal actionthrough a spout 37, from which they'are taken in a cleaned state. Theshaft 36 is driven continuously by means of miter-gears 38 and 39, theformer being attached to the shaft 36 and the latter to the shaft 21.Within the box or casing 32 and below the sieve 34 is arranged a sweeper40, which is fastened to the shaft As the beans are cleaned on the sieve34 the foreign matter passes down beneath the sieve to the bottom of thecasing 32 and is subsequently removed from the casing by the sweeper 40,which throws it into a spout 41, discharging the dirt and otherimpurities beneath the base 5 of the machine.

The blower 12 is driven by a belt 42, which passes from a pulley on ashaft 43, arranged horizontally in a bearing 45, mounted on the base 5,this hearing also serving as a step to the shaft 36. The shaft 43 isdriven by a miter-gear 4:6, meshing with the gear 39, as shown.

Having thus described our invention, We

' claim as new and desire to secure by Letters Patent-- 1. A screeningdevice, comprising a box or casing, a blank mounted in the top thereof,

a screen arranged below the blank, a spout leading from the blank andscreen, a gate lo cated at the receiving end of the blank to command thesame, a second screen located below the first screen and having a spoutfor the discharge of the material to be screened, an imperforate bottomreceiving the impurities from the second screen and provided with aspout for the discharge thereof and a fan working with the screens,substantially as described.

2-. In an apparatus for cleaning beans and the like, the combination ofa shaking screening device having a discharge-spout, a casing, a rotarybrush mounted in the casing,

and a feed-pipe attached to the brush and projecting up through the topof the casing into proximity with the spout from the screening device,the feed-pipe being of greater diameter than the spout, to insure thefeeding of the material from the shaking-spout to the feed-pipe.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
